Signature edit

Where can you edit your current signature used on the forum ?

(I only found the tagline)

You know why ? not only for estetic aspect but I have deleted several external links and I always say to the members, "but you can wear that link in your signature, and would appear in all your posts", they say "great, I'll do it" but I see no one has done that, now I know why... How do you do it ?

(some didn't like it very much the No External Link issue)

Wait I found it, but is kinda hidden.

Could it be a link in the Network "Edit Profile" to take you to "My settings" in the forum ? like "My Forum Settings"

(if cannot be in a single settings page) because that was the problem I was looking there.
